4mm apex seal
4mm would take more detonation then 3 mm would. there is a company already making 4mm abd 4.5mm. they shouldnt wear out housing since its only 1 mm thicker the turbo 3mm seal. what do u think?

All 86 and later rotaries have 2mm seals. Only the 85 and earlier 13b's had 3mm seals. In order to use 4mm seals you would have to substantially mill out the rotors. And honestly, from everything I've read you don't even need to use 3mm seals. Just get 2mm seals and tune it properly. 3mm seals also don't seal as well as 2mm ones, so I hate to think of 4mm seals.

(search the audio/visual section for a GREAT youtube link about the RE-5)To the orginal poster:
Im not aware of any company currently making anything larger than 3mm seals, but I would think going much larger than 3mm would severly reduce the "meat" left on the rotor which may result in pretty bad ending...but I could be wrong
I just know that the most common use of 3mm seals is for extremly worn 2mm seal slots.And as far as resistance to detonation is concerned, the whole idea is to use the rest of the setup to avoid it. Lots of high horespower rotaries use factory mazda seals, they are just tuned really well...thats the key

ya know what? this is *** backwards thinking....
early early 12A's had 6mm carbon apex seals, later 12A's had 3mm steel composite seals, 13B, BT, B RE, BREW and 20B engines all came with 2mm seals. why do you think that is? because tuning and precision manufacturing has come a long ways since the 60's, why are you insistent on proving every engineer since then wrong?

Its not just sealing but also weight, the reason they got away with 6mm carbons is because they are light, 4mm steal seals would have a redline of like 5000 rpm before they started chattering.
